Baader Planetarium has introduced the world's finest UV/IR cut filter. This filter is a must for all digital imaging with Digital Cameras, CCD Cameras, and modified WebCams. Also useful for protecting valuable H-Alpha filters from heat stress and damaging IR. Due to their extremely high optical quality, these filters may be stacked and used far in front of the focal plane (necessary for imaging uses). This UV-IR-Cut filter uses the very latest coating technology, to deliver the finest filtration quality.

Baader Planetarium UV/IR Cut / L-Filter Features:

Filter Durability: Filter durability has always been a hallmark of Baader Planetarium. The multi-layer dielectric coatings are plasma assisted and Ionbeam hardened using the latest technology (the coatings are harder than the glass substrate itself!). Baader filters withstand repeated real-world exposure to the elements and physical cleaning. Users need not leave their precious filters dull and dust encrusted to avoid cleaning - Baader filters may be used and cleaned without fear. We have heard sad stories from owners of other less durable filters, who have seen their coatings degrade from normal exposure to moisture, or wiped away from routine cleaning. Some manufacturers of astro filters resort to coating large sheets of bulk glass, then literally cutting or breaking their filters from the precoated sheets, ripping and tearing the coating's edges in the process - leaving the edges susceptible to moisture penetration and coating peel. This literal shortcut gives a manufacturer the ability to reduce stock and easily produce filters on demand or to readily produce odd sizes, but it comes at the expense of the customer by producing an inferior filter with greater risk of coating failure. Other filters are produced by sandwiching their delicate coatings in between two layers of glass (and risking blurred double images as well as eventual degradation from the edges inward). Baader Filters will truly last lifetimes. Though we don't recommend trying this yourself, Baader filters have passed rigorous military durability tests that subject the filters to boiling water for several hours, then comparing spectral traces before and after. The Baader filters pass this test with no coating degradation.

Freedom from Ghosts and Halos: Baader Planetarium's filters have always been halo and ghost free. Baader balances each dielectric coating stack to avoid the ghosts and annoying halos that plague other manufacturers filters.

Stackability: Unlike most other filters, Baader Planetarium filters are truly designed to be stacked and combined. This is possible due to the high optical quality and highly efficient anti-reflection multicoatings. The ability to combine filters opens up many interesting possibilities, permitting unique spectral characteristics unachievable with any single filter.

I bought this filter for planetary imaging, and to block the IR/UV light reaching my modified full spectrum DSLR. It does exactly as the description states. Whatever object I image, whether it's deep sky or planetary, I always have this filter in my optical train. A huge benefit of this filter is the stacking benefit, using other Baader filters with it will not alter the path of the light, allowing perfect focus across all light spectrums. This filter will kill the purple colour on Jupiter's belts, letting you concerntrate on getting the right white balance for a true natural colour.
